Transport to HI-STORE CISFSpent nuclear fuel will arrive at the HI-STORE CISF by railRobust and safe transport casks using specialty designed railcarsTransportation of radioactive material including Spent Nuclear Fuel isstrictly regulatedThe Nuclear Regulatory Commission (NRC) and the U.S. Department ofTransportation (DOT)Two transport casks designed and licensed with the NRC by HoltecInternational will be usedHI-STAR 190 (licensed) and HI-STAR 100MB (pending)www.holtec.com Page 21

Transport to HI-STORE CISFThere are two options for transporting the wide range ofcommercial SNF canister designs:Utilize the original transport cask that was approved for the canisterTransport in a Holtec Transport Cask (HI-STAR 190 and HI-STAR 100MB)Licensing non-Holtec canisters is not a technical issue for HI-STORMUMAXIn process of licensing for MPC-37, MPC-89, and TN-24PT1For transport the canister is not the containment boundarywww.holtec.com Page 22

Transport to HI-STORE CISFTransport casks are designedand fabricated to safelyconfine the fuel and shieldworkers and the public fromradiationMultiple layers of steel, lead,and other materialsInside the cask, the used fuel,in solid form, is contained inanother sealed canisterFully loaded casks weigh 125tons or more for rail shipmentswww.holtec.com Page 23Holtec Transport Cask

Rail Access to HI-STORE CISFLocation (distance) of the existing rail terminal from the site3.8 miles west Southwestern Railroad (SWR)32 miles east Texas-New Mexico RailroadThe local area has a well-developed rail road infrastructure. The length of additionalrail spur required for the site in less than 10 miles.The transportation rail car is transferred to a newly constructed rail spur locatedalong State Highway 243, where the transportation casks remain on the rail car andare transported approximately 5 miles east to the HI-STORE CISF.www.holtec.com Page 24Purple Line From Left Is Railroad Spur

Transport of Spent NuclearFuel is Proven and SafeAccording to a report prepared by Oak Ridge National Laboratoryand Argonne National Laboratory (2016):More than 25,000 shipments of used nuclear fuel have been madeworldwide, shipping more than 87,000 Metric Tons of Fuel.All shipments were undertaken without any injury or loss of lifeAccording to the NRC, more than 1,300 used fuel shipments havebeen completed safely in the United States over the past 35 yearsMost of the used fuel was shipped by railAll shipments were completed with no release of radioactivityThe U.S. Navy reports that, over the past 60 years, it hascompleted nearly 850 shipments of used fuel from navalpropulsion reactors, covering 1.6 million transportation miles.All shipments were completed with no release of radioactivitywww.holtec.com Page 25
